SUMMARY NOTES IN THE RECORD s20391 (Duration: 20:48:28.000) Starting time, recording date: 18:01:00 21/03/1992 Lead 0: 0 Lead 1: 1 Age: 64 Sex: M Comments: This record shows numerous shifts in QRS axis, in the absence of ischemia. There are some noisy periods. Lead 0: There are 2 ischemic episodes. Lead 1: There are corresponding ischemic episodes, but one of them is divided into two separate episodes by a very brief period of ST deviation which returned to the normal range. Electrode locations were not recorded. Symptoms during Holter recording: None reported Diagnoses: Coronary artery disease Insulin-dependent diabetes mellitus Treatment: Medications: Aspirin Nifedipine Atenolol Insulin Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: Angina, mild Hypertension: No Left ventricular hypertrophy: No Cardiomyopathy: No Valve disease: No Electrolyte abnormalities: No Hypercapnia, anemia, hypotension, hyperventilation: No Atrioventricular nodal conduction delay: No data Intraventricular conduction block: No Previous Myocardial Infarction: No Previous tests: ECG stress test: Yes Date: January, 1992 Findings: 2 mm ST depression.
